Non-ionizing Radiation
General safety precautions while using lasers include:
- Wear appropriate protective eyewear.
Wear appropriate protective eyewear.
- Use minimum power/energy required for the project.
- Reduce laser output with shutters/attenuators.
- Terminate laser beam with beam trap.
- Use diffuse reflective screens, remote viewing systems, etc., during alignments.
- Remove unnecessary objects from the vicinity of the laser.
- Keep the beam path away from eye level (sitting or standing).
- Don't put your body parts (especially the eyes) in the beam.
Protection Strategies
The following three strategies are effective in reducing excessive exposure to ionizing and non-ionizing radiation:
- Time: The amount of radiation exposure increases and decreases with the time workers spend near the source of radiation.
- Distance: The further workers are from a radiation source, the less their exposure.
- Shielding: The greater the shielding around the radiation source, the smaller the exposure.
